The explanation in msdn is too brief to me.
FILE_SYNCHRONOUS_IO_ALERT
All operations on the file are performed synchronously. Any wait on behalf of the caller is subject to premature termination from alerts. This flag also causes the I/O system to maintain the file-position pointer. If this flag is set, the SYNCHRONIZE flag must be set in the DesiredAccess parameter.
Any wait? For example, when WaitForSingleObjectEx's bAlertable is FALSE?
In fact, I'm not clear about the concepts. Does it mean that ZwReadFile/ZwWriteFile (in synchronous mode) will
returned prematurely when there are APC's?

i wrote a small code to test the ADC in atmega16 , the code doesn't contain errors but i tried to simulate the code on proteus and it doesn't work
here is the link for the code and proteus file i used to simulate
http://uploading.com/files/cb852548/adc.rar/
it is very simple but it doesn't work 
i wish anybody can help ,
thnx in advance .

People are unlikely to download and unpack some packed file just to help out. Paste the relevant code (inside PRE tags!) if you think it's useful. Also explain "doesn't work", it is not informative at all.

thnx very much , it has just worked
|

then you could add the solution so others might benefit.

i will explain the problem and the solution :
i wrote a code just to take an analog i/p and convert it to digital then send it to portc
and the output could be seen on leds connected to portc
the could is easy and has no errors :
.include "m16def.inc"
.def temp = r16
.org $000
rjmp start
start:
cli
ldi temp,$5f
out spl,temp
ldi temp,$04
out sph,temp
ser temp
out ddrc , temp
clr temp
out ddra , temp
rcall adc_initial
sei
Main_loop:
in temp , adch ;read adc high
out portc , temp
rjmp Main_loop
adc_initial:
sbi acsr , acd
ldi temp , $60 ;single i/p (ADC0)
out admux , temp ; *1 gain - left adjust result
;ref = Vcc
ldi temp , $a6 ;adc enable - auto trigger
out adcsra , temp ;/64 prescaling - no interrupt
ldi temp , $00 ;free running mode - no pull up
out sfior , temp
sbi adcsra , adsc ;start conv
ret
when i simulated the program on proteus it doesn't work at first , because i used to connect the AVR without connecting the Vcc pin and it was working so in all programs with no problems , but in this code you have to connect the Vcc pin

Sounds like a really detailed simulator. I'd think if external power was being applied would be overkill. Out of curiosity what happens in the simulator if you connect VCC to 50VDC or 120VAC instead of the 5(3.3?)VDC the chip being simulated is expecting. Does it error out with "Magic smoke released!"?

Initially it runs faster, and then it blows up. What did you expect?

I sh*t you not; I’ve never asked a question neither here nor in MSDN or other programing forums.
Here is my problem – my Alienware suddenly lost the monitor drivers and set them to some basic monitor with no 1920x1200 resolution option. I removed the driver, restarted the thing and it still insists that I have some old CRT monitor instead of 22’’ Dell widescreen. I’m out of ideas how to fix this without a system restore. The OS is Weven and my best guesses what causing this mess are:
0. I’m not using a DVI cable, so this could confuses the OS.
1. MS Security Essentials cleaned a couple of nasty viruses two weeks ago, so they could have left some crap behind.
Any ideas beyond the obvious “format-reinstall” routine?

Try Microsoft Update to see if it updates your drivers (you will have to choose the custom option so you can select hardware updates).
If that doesn't work, go find the drivers and install them manually.
If that doesn't work, find the drivers for your video card and install them manually too.

Maybe. Above a certain resolution, VGA looks crappy. Not sure if you are actually prevented from doing so though.

Already tried to update VGA and Monitor drivers from the device manager – regarding Windows there are no new versions.

This sound reasonable, I’m gonna try it today after work, thanks.

It used to work for me, at least until now.

Yes please, and while you are at it you might want to give back your degree certificate to the university

I would try, but they won’t let me to step back in the uni. I have a 10 kilometers restriction order from the campus.

Do you have the "Works on my machine[^]" certification?
(Also: do you mind if I move this thread to the Hardware forum?)

I've had this happen to a machine only after a Windows Update. Have you installed any lately? If so, you might try rolling back to a Restore point before the change to see if that helps.

I’ll try this too, thanks.

You need to reinstall the video card drivers I would say.

Silly question:
At home I have two PC's both with Gigabit NICs, plus an Epson BX310FN network printer and a Media Player (definitely 10/100MHz).
Currently, I use a Netgear DG834G modem router.
I have just bought a Gigabit NAS and am wondering if it is worth upgrading the router and cables to CAT6/gigabit. Will the printer work at Gigabit if I do upgrade? Will it slow everything else down? The tech specs don't appear to list the network speed it copes with and I am not sure if you can mix Gigabit and 100Mhz on the same router.
Real men don't use instructions. They are only the manufacturers opinion on how to put the thing together.

No, the speed of tx/rx is determined by the LAN HW on the device.

No.

I didn't think it would, but I am reluctant to replace working cabling, router, etc. if I wasn't sure. If it ain't broke, don't fix it certainly applies to cables-in-walls (even if they are in trunking). Unless you are going to get some real benefit and the wife won't notice until it is all working again of course...
So let's have a look for a five+ port gigabit ADSL router with wireless and CAT6 cables...
Thanks!

I thought it used to be that some budget hardware fell back to the speed of hte slowest attached device. Am I misremembering or has that limitation been removed from even the cheapest networking gear today?
